Remote VPN Cannot access Site-to-Site subnets - Cisco ASA 5505

Hi Everyone, 


We had to completely reinstall our Cisco ASA5505 which is the router connecting all our branch sites. All the sites are connecting fine but I'm having headaches trying to figure out why the remote users cannot reach my site-to-site subnets. It was working before so I know the problem is on this router.

Any help would be greatly appreciated! 

Our main site network is 192.168.1.0/24
Site-to-Site Networks are 192.168.2.0/24 & 192.168.3.0/24 & 192.168.4.0/24
Remote VPN network is 192.168.140.0/24

Running config:

ASA Version 8.2(5)

Hi,

Try this command: same-security-traffic permit intra-interface

You are coming in on the outside interface and attempting to go back out the outside interface. That command is needed for VPN hairpinning.

Please let us know if helpful.
